The synthesis of 5,5-diphenyl-5H-dibenzo[b,d]silole (3) resulted in a satisfactory yield of 60.7%, yielding a white solid. This was achieved by reacting the prepared 2,2-dibromobiphenyl (2) in the yield of 78.7%, obtained through the reaction of 2,2-dibromobenzene (1) as the starting material, with n-butyllithium and followed by dichlorodiphenylsilane in tetrahydrofuran solvent. Compounds 2 and 3 were characterized using ¹H, <SUP>13</SUP>C, <SUP>29</SUP>Si NMR, FT-IR, and UV-vis spectral data. Additionally, their thermal stability was assessed using thermogravimetric analysis. The structural conformity of compounds 2 and 3 with the proposed reaction scheme 1 was confirmed, and further validation was performed through DFT calculations. The prepared compounds 2 and 3 exhibited exceptional stability, with a weight loss not exceeding 1% up to 100℃ under a nitrogen atmosphere. The electrochemical properties of compound 3 were evaluated, revealing a C-rate performance of 1,016 ㎃hg<SUP>-1</SUP> at 0.2 A/g and a long cycling performance of 1,909 ㎃hg<SUP>-1</SUP> with a Coulombic efficiency of 90.8% after 500 cycles.
